Abstract:
Objective To observe the effectiveness of transferring human A20 gene into endothelial cells. Methods The shuttle plasmid pCAGGSEHA20 was constructed using gene cloning and recombined technique. Endothelial cells were transfected with pCAGGSEHA20 and pMAMneo by DOTAP. The postive cell clones were selected with G418. The stable transfection and expression of A20 in the endothelial cells were determined by in situ hybridization and immunohistochemical analysis. Results The two fragments digested from pCAGGSEHA20 by EcoRⅠ represented 4 6?kb and 2 3?kb by electrophoresis, which were confirmed to be the carrier and the A20 gene fragments inserted originally. The above results indicate that the construction of pCAGGSEHA20 was successful. Abundant A20 stable expression in endothelial cells transfected with pCAGGSEHA20 was confirmed by in situ hybridization and immunohistochemical analysis.Conclusion By means of the DOTAP, hA20 gene can be transferred and stably expressed in endothelial cells.
